catena-Poly[[bis­(4-chloro­methyl­pyridine-κN)cobalt(II)]-di-μ-dicyanamido-κ²N¹:κ²N⁵]

The title compound, [Co(C₂N₃)(C₆H₆ClN)₂]_n, is a polymeric cobalt(II) complex with the metal ion located on an inversion centre. The Co^II ion is six-coordinated by two N atoms of two 4-chloro­methyl­pyridine ligands and four N atoms from four dicyanamide ligands, forming a slightly distorted octa­hedral configuration. In the crystal structure, neighbouring Co atoms are linked together by double dicyanamide bridges to form a polymeric cobalt(II) complex.
